Directions: Solve each problem. Read carefully to be sure you know what the problem is asking. Draw rectangles to help you solve. 1. The perimeter of a rectangle is 70 feet, and the length is 25 feet. What is the width of the rectangle?
Answer:
10 feet
Step-by-step explanation:
Perimeter of a rectangle =2(l+b)
2(25+b)=70
50+2b=70
CLT
2b=70-50
2b=20
Divide both sides by 2

how do I do this question?
Answer:
Choice C
Step-by-step explanation:
We are given the function:
[tex]\displaystyle \large{f(x)=3x+5}[/tex]
Let [tex]\displaystyle \large{y=f(x)}[/tex] therefore:
[tex]\displaystyle \large{y=3x+5}[/tex]
To find an inverse of function, swap the position of x and y:
[tex]\displaystyle \large{x=3y+5}[/tex]
Then solve or simplify the equation in term of y:
[tex]\displaystyle \large{x-5=3y}\\\displaystyle \large{\frac{x-5}{3}=y}\\\displaystyle \large{y=\frac{1}{3}x-\frac{5}{3}}[/tex]
Therefore, the answer is choice C.
__________________________________________________________
Summary
An inverse function is a function that swaps the position of domain and range, defined as notation [tex]\displaystyle \large{f^{-1}(x)}[/tex] or [tex]\displaystyle \large{y^{-1}}[/tex] generally. When finding an inverse function, make sure to swap position of range and domain, if given the interval.
Only one-to-one functions may have an inverse — multiple-to-one can not have an inverse such as quadratic function or any even-degree polynomial functions.

the important thing you need to know in solving mathematics is to understand the question and the formulae that follws.for finding equations ur general formulae us:
y-y1=m(x-x1)
do not solve y and x.
the y1 and x1 are ur x and y values from ur coordinates respectively.
m is ur gradient or slope given.
plug in the values.
Step-by-step explanation:
y-y1=m(x-x1)
y-4=2/5(x-(-2))
the x-(-2) will change to positive thus giving you an equation of:

Which of the following functions will represent $500 placed
into a mutual fund yielding 10% per year for 4 years.
• A = 500(.10)^4
• A = 500(1.1)^4
• A = 500(4)(.10)
• A = 500(1.04)^10
Answer:
the answer is the first one
Step-by-step explanation:
The functions will represent $500 placed into a mutual fund yielding 10% per year for 4 years is A = 500(1.1)^4
what is Compound Interest?In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest.
given:
P= $500
First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 500.00[tex](1 + 0.1/1)(1)^4[/tex]
A = 500.00[tex](1.1)^4[/tex]
A = $732.05
Hence, the functions will represent $500 placed into a mutual fund yielding 10% per year for 4 years is A = 500(1.1)^4

The length and width of a rectangle are in the ratio 3:4. The perimeter of the rectangle is 84 cm. Find the length and width of the rectangle.
The length of the rectangle is 18 cm, and the width is 24 cm as per the concept of perimeter.
Let the length of the rectangle be 3x and the width be 4x, where x is a common factor.
The perimeter of a rectangle is given by the formula:
Perimeter = 2 × (Length + Width)
Given that the perimeter is 84 cm, we can write the equation as:
84 = 2 × (3x + 4x)
Now, let's solve for x:
84 = 2 × 7x
42 = 7x
x = 42 / 7
x = 6
Now that we have the value of x, we can find the length and width of the rectangle:
Length = 3x = 3 × 6
= 18 cm
Width = 4x = 4 × 6
= 24 cm
Therefore, the length of the rectangle is 18 cm, and the width is 24 cm. The length and width are in the ratio 3:4, and the perimeter of the rectangle is indeed 84 cm.

Step-by-step explanation:
This is just recalling the formula.
a bus travelled 63 km in first hour 60 km in second hour and 57 km in third hour what was te Average distance covered in one hour
The average speed is the ratio of the total distance to the total time. Then the average distance covered in one hour by the bus is 60 kilometers.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
[tex]\rm Speed = \dfrac{Distace }{Time }[/tex]
A bus traveled 63 km in the first hour 60 km in the second hour and 57 km in the third hour.
Then the average speed will be
[tex]\rm Average \ speed = \dfrac{Total \ distace }{Total \ time }\\\\\\Average \ speed = \dfrac{63 + 60 +57}{1+1+1}\\\\\\ Average \ speed = \dfrac{180}{3}\\\\Average \ speed = 60 \ km/h[/tex]
The average distance covered in one hour by the bus is 60 kilometers.

Please help I really need it I’m so bad at math worth 20 points for 1 question please
Answer:
20
Step-by-step explanation
use the formula a²+b²=c²
since a=21 and c=29 you need to solve for b
Put 21 in for a and 29 in for c
21²+b²=29²
21²=441
29²=841
so then the equation would be 441+b²=841
subtract both sides by 441
then you have b²=400
now just find the square root of 400
√b²=√400
b=20

Line a is parallel to line b. If the measure of <7 is 114 what is the measure of <4?
Using opposite by the same vertex and supplementary angles, it is found that the measure of angle 4 is of 66º.
What are opposite by the same vertex and supplementary angles?When two parallel lines are cut by a transversal, angles that are opposite in a vertex are congruent, that is, they have the same measure.When two angles are supplementary, the sum of their measures is of 180º.In this problem, angles 5 and 7 are opposite by the same vertex, hence:
m<7 = m<5 = 114º.
Angles 4 and 5 are supplementary, hence:
m<4 + m<5 = 180º.
m<4 = 66º.
The measure of angle 4 is of 66º.
